Name the pulmonary disease in which alveolar surface area involved in gas exchange is drastically reduced due to damage in the alveolar walls.

  • Pleurisy

  • Emphysema

  • Pneumonia

  • Asthma

Answer

C.

Pneumonia

Empysema is a chronic respiratory disease where there is over-inflation of the air sacs(alveoli) in the lung, causing a decrease in the lung function and often, breathlessness. In this disease, the alveolar walls are damaged leading to drastic reduction in gas exchange.
